soul blade (the prequal to soul calibur) its the weapon master mode and how it explores the journey and the lives of the characters alot more than any other fighter.....a runner up would be soul calibur 1 (because the action was slowed down for SC2 and the mission mode was better in SC1) and third place goes to tekken 5 (for the inclusion of the arcade modes of tekken 1-3 and the large array of characters plus the story aint that bad either)
